Brit showed off her smile by wearing a highly flattering lipstick shade. Looks like she took a cosmetic cue from Madonna, whose tour makeup is by Shu Uemura. But you don't need to be a pop superstar to get Britney's look — she's wearing Shu Uemura Rouge Unlimited lipstick ($23) in BG 940. Gorgeous!

She looks amazing!! Better than I've seen her look in years.
Although I must admit, seeing her on stage with Madonna, her outfit looked kind of strange. She was dressed like she was going to a business meeting or something. It just looked weird with what Madonna was wearing. But gorgeous nonetheless!
